<h2>Data set for Unstructured Treatment Interruption Study</h2>

<h3>Description</h3>

<p>Data set from a study of Unstructured Treatment Interruption in HIV-infected adolescents in four institutions in the US.  The main outcome is the HIV-1 RNA viral load, which is subject to censoring below the lower limit of detection of the assay (50 copies/mL).  The censored observations are indicated by the variable RNAcens</p>


<h3>Usage</h3>

<pre>data(UTIdata)</pre>


<h3>Format</h3>

<p>A data frame with 373 observations on the following 5 variables.
</p>

<dl>
